[Zope] tacker error

[Mick]

I have the following error when trying to view a trackerWiki on Zope 2.3.3,
i.e. the product adds ok, but when clicking on it to try and view it I get
the error. The product is the latest CVS snapshot of tracker from
http://www.zope.org//Members/klm/TrackerWiki/

Error Type: TypeError
Error Value: __str__ returned non-string (type tuple)

I have submited a bug report, but was wondering if someone had seen the same
problem.

thanks
Mick
